When considered as unsigned numbers (在它們視作無符號數(shù)時(shí)) 。
1 may be either a signed number or an unsigned number depending on context 依上下文1可以是一個(gè)有號數(shù)或是一個(gè)無號數(shù)
Which represents a base 10 unsigned number , is prefixed with a negative sign ,它表示一個(gè)10為基的無符號數(shù),前面帶一個(gè)負(fù)號。
Which represents a non - base 10 unsigned number , is prefixed with a negative sign ,它表示一個(gè)非10為基的無符號數(shù),前面帶一個(gè)負(fù)號。
2 may be either a double - cell signed number or a double - cell unsigned number depending on context 依上下文2可以是一個(gè)雙單元有號數(shù)或是一個(gè)雙單元無號數(shù)
The storage unit for the character data type ( c @ , c ! , fill , etc . ) must be able to contain unsigned numbers from 0 through 255 一個(gè)實(shí)作不需要限制字元儲存到這個(gè)?圍,但是一個(gè)沒有環(huán)境相依性的程式不能假定在一個(gè)字元位置儲存在這個(gè)?圍之外數(shù)目的能力
